My Sunday afternoon snooze got a little long

From the factory it has 56/40 primary needles in it, then I installed 58/44's in. I have some 54/38's that I did not try but they have a smaller diameter which would be going the wrong direction in my mind. So now I have 58/44 primary needles.

Factory primary jets are 89 with 91 and 87 in my kit, I installed the 87

Factory secondary is 86 with 88 and 84 in the kit, I installed 84

I still have the factory 6" hg step up spring in it.

These are the jets available in the 625 cfm kit which will fit in my 750

Primary main jet assorment of .074, .076, .080 and .082
Secondary main jet assortment of .078 and .082
Metring rod assortment of .056/.048, .058/.050, .058/.052, .060/.050, .062/.054 and .064/.056
Step-Up spring assortment of orange, blue, yellow and silver springs
